摘　　要：基于CES生产函数形式,文章推导了出口商品供给价格弹性的表达式。根据中国1997年至2017年的能源数据,文章计算出中国出口能源的供给价格弹性值。文章计算结果显示,中国出口能源供给价格弹性值为0.868266。从出口能源品种上看,中国出口能源商品供给价格弹性值存在很大的差异性。文章计算结果显示,中国出口煤炭的供给价格弹性值为-1.328703,中国出口石油的供给价格弹性值为-3.148054,中国出口电力的供给价格弹性为0.335038。Based on the CES production function form,this article derives the expression for the price elasticity of export commodity supply.Based on China's energy data from 1997 to 2017,the article calculates the supply price elasticity of China's exported energy.The calculation results of the article show that the price elasticity of China's export energy supply is 0.868266.From the perspective of exported energy products,there are significant differences in the price elasticity of China's exported energy commodity supply.The calculation results of the article show that the supply price elasticity of China's exported coal is-1.328703,the supply price elasticity of China's exported oil is-3.148054,and the supply price elasticity of China's exported electricity is 0.335038.
